Abstract
A door exit device may include an actuator, an upper latch, and a lower latch. The actuator may be operatively coupled to the upper latch by a first drive and to the lower latch by a second drive. Each drive may include a housing which is mountable to the exterior of a door panel and a drive rod slidably supported within the housing. The housing may include a base which is mountable to the door panel and a cover attachable to the base with the drive rod located between the base and the cover. The housing may be configured to extend from the actuator to the latch to conceal the entire length of the rod between the actuator and the latch.
